SPECIFICATION forming part of Letters Patent No. 67' 0,816, dated March 26, 1901.

Application filed January 5, 1900. Serial No. 455. (No model.)

T0 a/ZZ whom, t 1mg/j concern:

Be it known that I, DAVID HENRY SAUN- DERS, a citizen of the United States, residing at 13 Addison street, Gloucester, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Box- Hinging Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in box hinging machines for the purpose of automatically hinging wooden or other boxes by means of intei-locking wire staples and it consists of the novel combination and arrangement of parts hereinafter more particularly described, illustrated in the accompanying drawings, and particularly pointed out in the claim hereunto annexed.'

Fig. 28 represents a detail side elevation of the receiver-bar and receiver, and Fig. 29 represents a detail side elevation of the male former.

Similar letters refer to similar parts wherever they occur on the different `parts of the drawings.

In the drawings, A represents the base or pedestal, to which is secured the gooseneckframe BB', as shown. In the frame portion B' is journaled a rotary driving-shaft C, on which is loosely journaled a pulley D, to which a constant rotary motion is applied by means of belt-power, as usual. A suitable or well-known clutch is interposed between said pulley D and shaft C, which clutchlis IOO preferably actuated by a spring-pressed pedallever E and suitable intermediate connecting mechanism, as is common in clutch starting and stopping mechanism for machines in which the depression of a pedal-lever will cause one complete rotation to be imparted to the driving-shaft. Such clutch mechanism forms no part of my present invention, and need therefore not be described in detail.

On the driving-shaft C is secu red a disk C', provided with a crank-pin C", pivotallyconnected to a link C3, the forward end of which is pivotally connected to a rock-lever F, secured to a shaft f, journaled in a sleeve g, which latter is journaled in a bearing in the forward portion of the frame B', as shown in Figs. l, 24, and 25. Io the other end of the ,rock-shaftf are secured levers F' F', suitably connected to the staple-driving devices, as will hereinafter be more fully described.

To one end of the sleeve gis secured a lever G, the lower end of which is pivotally connected to a link G', to which a longitudinal reciprocating motion is imparted by means of a cam G", secured to the driving-shaft O, said cam engaging pins or pins and rolls g" g" on the link G', as shown in detail in Fig. 22. To the opposite end of the sleeve g are secured the levers G3 G3, which are suitably connected to the female former-bars, by which the staples are formed and the receiver-bars actuated, as will hereinafter be described.

In this machine I make use of a pair of' stationary guides or cases, arranged, preferably, at a right angle to each other, each 'of said guides or cases containing a laterallymovable male former and a longitudinallymovable female former for the purpose of bending the pointed staple-wire blank into the form of a staple, each such guide or case also containing a longitudinally movable driver-bar for driving the finished staple and a longitudinally-movable throat or st-aple receiver, in which the staple is forced by the driver previous to the driving operation and guided therein during the staple-driving operation. Such longitudinally-movable staplereceiver is moved downward toward or in contact with the box and cover previous to the driving of the staple by means of the female former-bar, which during its descent comes in contact with the said throat or receiver and holds the latter in contact with the box and cover, or nearly so, during the staplenally movable thel female former-bar I and driver-bar K. The female former-bar I is reciprocated by the rocking lever G3, which is pivotally connected to said former-bar by means of a link g3, as shown in Fig. 2. The driver-bar K is reciprocated by the rocking lever F', which is pivotally connected to said driver-bar by means of a link f', as shown in Fig. 2. To the lower end of the former-bar I is secured the female former (Shown in Figs. 15, 17, and 26 and in dotted lines in Fig. 21..)

7c is the driver, secured to the lower end of the driver-bar, as shown in Figs. 15, 16, 17, 18, 20, 21, and 27.

L is the throat or receiver, attached to or made integral with the lower end of the receiver-bar Z, which is normally held raised, as shown in the right-hand portion of Fig. 15 and left-hand portion of Fig. 18, by the influence of a suitable spring M. (Shown in Figs. 15 and 17.)

The throat or receiver L is automatically forced downward toward or in contact with the box N and cover N', as shown in the lefthand portion of Fig. 15 and right-hand portion of Fig. 18, during the driving of the staple, and such downward motion of said throat or receiver is caused by the lower end of the female former-bar I coming in contact with the throat or receiver during the downward movement of said former-bar after the staple has been formed. After a staple has been driven and the female former-bar I raised upward the throat or receiver L is automatically raised to the position shown in the right-hand portion of Fig. 15 and lefthand portion of Fig. 1S, by the influence of the spring M, in which position it remains until another staple has been formed and ready to be driven.

In the operation of the machine the throats or receivers L are alternately held against the box and cover and raised above the same, so as to cause one of said receivers to get out of the way of the other.

In. combination with the longitudinallymovable female former t' I use a laterallymovable or oscillating male former O, which is pivoted to the case H at O', as shown in IOO IIO

Figs. 15, 17, and 29, and said male former is provided with a notch or recess O3, adapted to receive the wire P previous to its being cut off to the desired length for 'the formation of the staple P'., and the said wire after being cut off to the desired length is retained in said notch until the female former in its descent causes the staple to be formed by being bent on the opposite sides of the male former. After the staple has thus been formed the male former is pressed outward to the position shown in the left-hand portion of Fig. 15 by the receiver-bar Zcoming in contact with a cam projection O4on said male former, thus automatically moving the male former out of the way of the staple, so as to allow it to be driven during the descent of the driverbar and its driver.

The various parts comprising the staple forming, guiding, and driving devices in one guide or case H are arranged at a right angle to the corresponding parts in the other guide or case, so as to make and drive one staple at a right angle to the other.

To each of the staple forming and driving devices is fed a wire P from a reel P", and in practice I prefer to feed such wire through a guide or track Q. (Shown in Figs. 2 and 3.)

In connection with this machine I use for each of the two staple forming and driving devices an intermittent wire feed device, preferably composed of a pair of feed-rollers R R', geared together and secured, respectively, to shafts r r', journaled in bearings in the frame portion B', as shown in Figs. 2 and 3. To one end of the shaft r is secured a gear r", the teeth of which mesh in the teeth of a segmental gear R3, secured to a shaft r3, journaled in a bearing in the frame portion B', as shown in Figs. l and 4:. 'Ihe segmental gear R3 is provided with a forked arm or extension R4, to which an intermittent rocking motion is imparted by a pin or pin and roll K', attached to the upper end of the driver-bar K, as shown in Figs. 2, 15, and 17. The feed of the Wire takes place during the downward movement of the driver-bar K, which causes the feed-rollers R R to turn in the direction of arrow shown in Figs. 2 and 3. During the upward movement of the driver-bar K the segmental gear R3 and its forked arm R4 are automatically moved to the position shown in Fig. 2, and during such movement the wire-feed rollers are held stationary by means of any suitable pawl-andratchet mechanism usually employed in intermittent feed devices for this purpose. In connection with such intermittent feed mechanism I prefer to employ any well-known device or mechanism for regulating the length of the wire that is being fed, according to the size or length of the staple that is to be formed.

I wish to state that I do not desire to conne myself to any particular construction of the intermittent feed device or means for regulating the length of the feed, as this may be done in any suitable manner without departing from the essence of my invention.

In connection with this my improved boxhinging machine I use a wire pointing and cutting-off device, preferably constructed as follows: S is a stationary shear, and S' is a movable shear, between which the wire is fed previous to being formed and driven. The shear S' is moved downward across the face of the stationary shear S by means of a cam or projection R5 on the rock-shaft r3, as shown in Fig. 3, and after the wire has been cut and pointed the cam R5 is automatically released from said movable shear, which is then automatically raised above the stationary shear by the influence of a spring S", as shown in Fig. 3. The wire is fed to one of the cases or guides H at a right angle to the wire fed to the other guide or case, so as to cause the staples to be formed and driven interlocked at a right angle to each other.

With this machine I use an automatic mechanism for forcing and holding the box and cover against the under side of the frame portion B' or a projection thereon during the staple-driving operation, and it is constructed as follows: T T' represent the angular box and cover support, on which T is the vertical and T' the horizontal portion. Upon the vertical portion T is vertically adjustable a bracket T", upon which the bottom of the box N is supported during the box-hinging operation, as shown in Figs. l and 2. The bracket T" is yieldingly supported on a spring T3, interposed between the under side of said bracket and a vertically-adjustable stop or rest T4. (Shown in Figs. l, 2, and 7.) The object of the spring T3, which is interposed between the rest T4 and the lower part of the bracket T", is to com pensate for slight variations in the depths of the boxes that are being hinged. The rear portion of the cover-support T' is provided with a similar yielding bracket or gage t", bearing against a spring t3, interposed between said bracket and a rest or stop i4, adjustably secured to the box-support T', as shown in Figs. l, 2, 6, and 7, and this is for the purpose of compensating for the slight variations in the width of the covers that are to be hinged by the improved machine. The vertical box-support T is horizontally adjustable relative to a slide-bar U, that is guided upon and made vertically adjustable relative to the front portion of the frame B, as shown in Figs. l, 2, 6, 7, and S.

The object of making the box-support T horizontally adjustable is to enable the box and cover to be adjusted relative to the staple-driving devices, so as to cause the interlocking staples to be driven in such a position as to make the cover fit properly on the top of the box when the cover is closed thereon.

The slide-bar U is guided in vertical Ways on the front portion of the frame B, and to it is pivotally connected an adjustable link U', the upper end of which is pivotally connected to a rock-lever U", pivoted at U3 to the frame B and having at its rearend a pin o`r pin and roll U4, actuated by a cam U5, secured to the rotary driving-shaft C, as sho-wn in Figs. l and 23. The said cam U5 serves to move the box and cover supports upward, so as to hold the box and cover up against the underside of the frame portion B' or a projection thereon during the staple forming and driving operation. After a pair of interlocking staples has been driven through the box and cover,

respectively, the cam U5 ceases to act on the lever U", causing the box and cover supports The clamping device for automatically clamping the rear side of the box N against the vertical portion T of the box-support and clamping the cover N against the said rear side of the box and between it and the gage t" is constructed as follows: To the lever U is pivoted at@ a link V, the upper end of which is pivotally connected to a bell-crank lever V', the latterbeing pivotally connected to an adjustable link or rod V, the forward end of which is connected to a clamp-bar W, having a downwardly-extending clamping projection w, provided with a suitable clenching-surface and adapted to clamp the back of the box N against the vertical box-support T and front edge of the coverN, and to hold such parts properly clamped together during the staple forming and driving operation, as 'shown in Figs. l and 2. The clamp w is automatically released when the cam U5 ceases to act upon the lever U, at which time the upward pressure on the box and cover support is likewise released, enabling the operator to adjust or remove the hinged box and cover, as may be desired.

It will be noticed that in this my machine the two staple forming and driving devices are arranged at a right angle to each other in a vertical plane, so as to cause the staples from the said two devices to be driven properly interlocked through the lbox and cover, respectively, and it will also be noticed that the staple forming, guiding, and driving mechanism in one of said devices is arranged at a right angle to the corresponding parts in the other device for the purpose of placing one staple in position to be driven interlocked with the other staple.

The operation of the machine is as follows: The operator places a box-cover or box part N on the horizontal cover-support T and against the yielding gage t on such support and places the box or box part N upon the yielding bracket T of the vertical portion of the box-support, after which he starts the machine, causing the automatic clamping devices to force the box in close contact with the front edge of the cover and vertical portion of the box-support and causing the upper edge of the box and the cover to be confined and clamped between the verticallyadjustable box and cover support and a stationary projection on the frame of the machine, thus holding the box and cover rigidly clamped in position for receiving the wire staples, as shown in Figs. l and 2. During a previous partial rotation of the drivingshaft a Wire has been fed, cut, and pointed, formed into a staple, and placed into one of the throats or receivers, which, during such partial rotation of the shaft, has been moved downward toward or in contact with the box fst/031e and cover. The driver descends and causesl the staple to be forced through such throat or receiver and into and through the cover and clenched against the box and cover support. The throat or receiver and the staple forming and driving device are then automatically raised in position for forming and driving a subsequent staple, the blank for which has been fed and cut during the driving of the first staple. While the box and cover are still clamped in position the throat or receiver of the other staple forming and driving device descends toward or in contact with the box and cover, and the descent of its driver causes a previously-formed staple, cut olf from another wire fed at a right angle to the rst, to be driven through the box and clenched against the clamping device and in such a manner as to be interlocked with the previously-driven staple. The throat or receiver and the staple forming and driving device for said second staple are then automatically. raised in position for forming and driving a subsequent staple, the blank for which has been fed and cut during the driving of said second staple. The clamping device is then automatically released and the box-snpport lowered to its lowest position, enabling the operator to laterally adjust the position of the box and cover relative to the staple forming and driving devices for receiving another hinge in a manner as above described, or removing the hinged box and cover to be replaced with a fresh box and cover to be hinged together as before, and so on during the operation of the machine.

Having thus fully described the nature,construction, and operation of my invention, I wish to secure by Letters Patent and claim- In a box-hinging machine, a pair of pivoted spring-pressed alternately-operating laterally-moving male formers, each adapted to receive a cut of wire from which a staple is formed, a pair of alternately-operating longitudinally-moving female former-s adapted to engage the said cuts of wire for forming the same into staples, a pair of spring-actuated alternately-operating longitudinally-moving throats or receivers adapted to receive and automatically remove the said male formers,

IOO

from engaging with the staples, anda pair of alternately-operating longitudinally-moving driver-bars adapted to engage and drive the said staples in a box and cover for hinging the same together.
